Abstract

Aim: The aim of our study was to assess time course and regression of left ventricular end-systolic and end-diastolic diameters after aortic valve replacement. Methods: Between the period of January 2000 and December 2003, 20 of the patients who had aortic valve replacement due to aortic valve stenosis at the Cardiovascular Surgery Department of our Hospital were included in the study. There were 16 male and 4 female patients ranging in age from 18 to 70 years with a mean age of 36,51±18,10 years. Preoperative and postoperative echocardiographic evaluations were performed in all patients. Results: After aortic valve replacement there were significant hemodynamic improvements, with a fall in the left ventricular end-diastolic and end-systolic diameters, and interventricular septal wall thickness. Postoperative left ventricular ejection fraction was significantly greater than before surgery in all cases. Conclusion: Aortic valve replacement improves the left ventricular ejection fraction and provides the regression of myocardial hypertrophy.

Özet

Amaç: Çalışmamızın amacı aort kapak replasmam sonrası sol ventrikül sistol ve diyastol sonrası çaplarında olan değişiklikleri değerlendirmektir. Metot: Ocak 2000 ile Aralık 2003 tarihleri arasında Anabilim Dalımızda aort darlığı nedeniyle aort kapak replasmam yapılan hastalardan 20'si çalışma kapsamına alınmıştır. Hastalardan 16'sı erkek, 4'ü kadın olup yaşları 18 ile 70 arasında değişmekte ve ortalama yaş ta 36,51±18,10 yıl idi. Tüm hastalarda ameliyat öncesi ve sonrası ekokardiyografik değerlendirmeler yapıldı. Bulgular: Aort kapak replasmam sonrası tüm hastalarda hemodinami anlamlı olarak düzeldi. Sol ventrikül sistol ve diyastol sonrası çapları ile interventriküler septum kalınlığı azaldı. Ayrıca ameliyat sonrası sol ventrikül ejeksiyon fraksiyonu ameliyat öncesine göre anlamlı olarak yükseldi. Sonuç: Aort kapak replasmanı sol ventrikül ejeksiyon fraksiyonunu artırır ve miyokardiyal hipertrofinin gerilemesini sağlar.
